1n the putting up of goods in packages, and especially of food products, it is quite desirable to have the packages marked with the date on which the goods are put up so that the purchaser can tell whet-her he is purchasing goods which have been recently put up or not. Sometimes unscrupulous tradesmen represent that the goods have been recently canned or boxed when as a matter of fact they have been put up for av long time, and when the goods prove to be of inferior quality owing to their staleness, the purchaser, not knowing the cause for it, will sometimes blame the parties who pack the goods, thinking that it is through some 'l'ault of theirs in the packing or through some defectin the quality of the goods themselves instead of attributing the fault to the tradesmen who has unfairly sold to him stoic goods, and it is for the rotection of the man who puts up the goods t lat his packages should be marked in some way to indicate when they were ut u It is desirable also that the dealer s oul know for his own information just when the goods were put up,

- as it is im ossible for him to tell in all cases just how ong he has had them in stock.

Sometimes also it is desirable to stamp the ackages as they are put up with some other esi nating mark.

"The packaging of certain classes of goods which'are sold by the package is very largely dohe by machinery and also is to a large extent automatic.

I have invented a number of machines for both weighing and filling packages automatically, the general type of which is shown and described in Patent No. 714,875, dated December 2, 1902 and Patent No. 716,007, dated December 16, 1902. Those are both for weighing and filling. Sometimes, however, the packages are tilled without being weighed. In Patent No. 755,411 dated March 21, 1905 I have shown and described a machine for closing and sealing the ends of cartons after being fiilcd. My present invention is applicable to such a machine also.

One object. of the pi. t invention is to provide an attachment for the pin-large filling machine or sealing machine which is auto matically operated to stamp the packages with the date or any other designating mark desired.

For the purpose of illustrating and describing the invention, 1 have shown in the drawings the device as attached to a weighing and filling machine of the type shown in said Patents No. 714,875 and No. 710.007.

Another object of the invention is to provide means whereby the marking device may be combined. with a weighing and filling machine in such manner that the ti iping ol' the scale may actuate or control the nun-king mechanism.

As the details of the operation of the weighing and filling mechanism do not form a part of the present invention, only so much of the weighing and filling machine is shown as is deemed necessary to properly illustrate the resentinvention.

T to invention will be fully understood from the following description taken in connection with the accompanying drawings.

and the novel features are pointed out and clearly defined in the claims at the close ol the specification. 1

In the drawings,l igure 1 is a plan of a portion of a weighing and filling machine with an attachment embodying my invention. Fig. 2 is a side elevation, partly in section, on an enlarged scalc,"show1ng a portion of the package moving mechanism with the marking attachment. Fig. 3 is a detail plain on an enlarged scale showing the ackagc in engagement with the lever whici operates the marker so that further movement of the package will actuate the marker. detail plan similar to Fig. 3 after the package has mm ed far enough to bring the marker into engagement with the carton. Fig. 5 is a detail view of the marking disk. Fig. 6 is a detail of a portion of the machine showing a modified form of mechanism lor actuating the marking disk in which the lever which carries the marking mechanism is engaged directly by nv projection from the carton moving ring instead of by the package itself.

Referring now to the drawing 1 yes Fig. 4 is a sents a rotary ring package carrier which retates in a horizontal plane and is provided with a plurality of outwardly projecting package moving tin ers 2.

3 represents a ta 10 on which the empt cartons or other receptacles 4 are place( As the ring 1 rotates, one of the cartons 4 is engaged by one of the fingers 2 and pushed along on the track 5 to a position beneath the hopper 6 through which the goods are fed into the carton. Means are rovided to cause the ring 1 to rotate intermittently, the ring remaining stationary while the carton is being filled, the means for causing the intermittent motion not being shown in detail as it forms no part of the present invention and is well known.

In the form of the machine shown in the drawings, the circular track 5 extends beyond the hopper 6 so that after the cart-on is filled at the next movement of the carrier ring the filled carton will be pushed from beneath the hopper along on the track 5 and may then be removed in any manner desired.

In the machine shown in the drawings, which as previously stated, is of the tv e shown in Patents No. 714,875 and i\o. 716,007, the carton moving ring 1 is controlled by the tipping of the scale. The ti ping of the scale beam under weight of t io filled package actuates the mechamsm which shuts oil the feed and also causes the carrier ring 1 to start. When the scale tips, a reci rocating member is caused to move in a t irection to close the valve to the hopper 6 which is above the scales. The reciprocating frame mentioned comprises the two side rods 41 which slide in bearings 49 fixed to the side of the cylinder 44 and are connected at their ends by the two cross-heads 42, 43. In one end of a double chambered cylinder 44 is a piston whose stem is connected with the forward cross-head 42, aml in the other end of the cylinder is a piston whose stem 46 is connected with the rear cross-head 43. Between the two pistons is an air chest 47 connected with a compressed air chamber and having ducts, not shown, which lead into the two chambers of the cylinder 44, one chamber being in one end of the cylinder and the other chamber being in the other end, the two chambers being separated bv the air chest 47 and open at their outer cm s. Moving in the air chest 47 is a piston valve 48 which, as it rises and falls, admits air pressure alternately to the opposite chambers of the cylinder 44, and thereby drives the pistons 4:) and 46 and moves the reciprocating frame to open and close the'hopper valve.

The carrier ring 1 is intermittently driven by shaft through intermediate gear and clutch mcclnmism, not fully shown, being in part covered by the box 51, the forward movement of the reci )rocatin frame which closes the hopper val ve causing the clutch 1 mechanism to be brought into engagement so as to operatively connect the carrier ring 1 with the driving shaft 50 and the movement of the reciprocating frame in'the reverse direction to open the hopper valve causing the disengagement of the clutch and thereby cause the carrier ring to stop.

Mechanism is connected with the scale beam and with*the piston valve 48 which moves in the air chest 47, whereby the tipping of the scale actuates the valve 48 in such a direction as to admit pressure to one chamber of the cylinder 44 which drives the reciprocating frame in a direction to close the hoper valve, the movement of the reciprocating rame engaging the clutch mechanism, as previously described, to give movement to the carrier ring, and the movement of the carrier ring actuates mechanism which near the end of the movement of the carrier ring, moves the piston 48 in the reverse direction and admits pressure to another one of the chambers of the cylinder 44 and opens the scale hopper valve.

The marking attachment is located so that it will mark the carton either before or after it has reached the place of filling beneath the hop er according to whichever is desired. In the form of construction shown, it is located between the table 3, where the empty carton has started, and the ho per 6.

The marking attachment ant connections are as follows: Secured to, or forming a part of, the frame 7, which supports the carrier ring 1, is a bracket 8 which extends underneath the track 5 and radially outside of it, and has an upturned end 8' on which is mounted an are shaped arm 9 whose inner face 9 is formed as an ink pad. Mounted on a shaft 10, which has its bearings in a boss 11 having one arm 12 which extends into the path of the moving carton and another arm 12' which carries the marking disk 13. The bell crank lever is fast to the shaft 10, so as to turn with it, being made fast either by driving fit or in any other suitable way. The bell crank lever is formed with a boss 14 whose lower end turns on the upper end of the boss 11 when the shaft turns on its axis.

Pivoted to the upper side of the arm 12 of the rocking lever near its outer end by a stud 15 is the markin disk 13. The marking disk may be either fast to the stud l5 and the stud 15 turn in bearings in the arm 12, or the stud 15 may be fast to the arm 12 and the marking dlsk 13 turn on the stud. 'ihe stud 15 is provided with a head 16 which keeps the marking disk 13 from falling oil. Irc'crably the marking disk turns on the stud 15 which is screw threaded at its lower end and screwed into a hole tapped out in the arm 12. When the carton 4 continues its movement from the position shown in Fig. 3 where it engages the arm 12 of the rocking on the bracket 8, is a bell crank rocking lever causing the periphery of the markin isk to roll on the inner curved face of the in pad 9' until it moves past theend of the ink "pad,

and as the rocking lever is still further turned, the marking disk will engage the outer face of the carton 4 as shown in Fig. 4 before the carton has )assed out of reach. The engagement of the carton with the marking disk as the carton moves along, will cause the marking disk to rotate and mark the carton with whatever date or other indicating mark it is provided with.

In order to return the rocking lever to its normal position again after the carton has ridden past the end of the arm 12 of the rocking lever, a spring 17 is provided which is coiled around the shaft 10, one end of which is secured to the boss 11 on the arm 8 as by having an up-turned end 17' of the spring enter a slot in the boss, the other end of the spring being made fast to the shaft 10 or to ahead 18 pinned to the shaft 10 as by a pin 19 or it may be fastened in any other suitable way.

In order to make sure that the marking disk 13, when returned to its initial position, is turned on its axis into just the position so that when it moves forward again the marking or dating stamp will always be in the right position to enga e the carton when it moves forward instead of havin the back side of the disk en age it, the disk is provided on its upper face with two oppositely disposed pins 20 which respectively engage steps 21 at the end of the return movement so that if in any way the disk has during the movement become rotated out of position, whichever one of the pins 20 strikes its stop pin 21 first will cause the disk to turn on its axis until the other pin 20 strikes its sto 21 to bring it into the right position. 'liese stop pins 21 are shown as projecting from a block 22 screwed to the end of the holder in the ink pad 9.

In the modification shown in Fig. 6, the arm 12 of the. rocking lever is shown as ongaged by an arm 36 projecting directly from the carton moving finger 2. The arm 12 is shown as somewhat loxwer than in Fig. 1 and as extending at a slightly different angle from arm 12, so that the rocking lever will be turned at the proper moment for the markin disk to engage the carton. It is obvious that the location and form of rocking lever and of the projection from the )acka 0 moving ring which engages said roc ing ever may be varied.

While 1 have shown and described the rocking lever 12 as being engaged and actuated by the carton 4, it is obvious that instead of being actuated by the carton itself, it might be actuated by means of a finger projecting from the carrier ring 1 just in advance of the carton so as to swing the rocking lever around to bring'themarking disk into engagement with the carton at the proper time.
